What to do in an emergency IF YOU HAVE A FLAT TIRE (WITH TIRE MOBILITY KIT)
Air pressure loss in the tire may
adversely affect tire performance.
For this reason, you should avoid
abrupt steering or other driving
maneuvers, especially if the vehicle
is heavily loaded or if a trailer is in
use.
The TMK is not designed or intended
as a permanent tire repair method
and is to be used for one tire only.
This instruction shows you step by
step how to temporarily seal the
puncture simply and reliably.
Read the section "Notes on the safe
use of the TMK".
WARNING
Do not use the TMK if a tire is
severely damaged by driving run flat
or with insufficient air pressure. Only
punctured areas located within the
tread region of the tire can be sealed
using the TMK.
